PEM® Type SFN™ spinning flare nut is a one piece, flanged hex nut that installs by simply pressing it into a properly sized, prepunched embossed mounting hole. The nut is permanently captive and still spins freely in the sheet. This allows quick attachment to mating hardware, eliminating much of the need for loose fasteners.

Above the sheet, the part appears identical to standard flanged hex nuts, while on the other side, the part remains flush.

The spinning flare nut eliminates loose hardware such as flange nuts. When used with a self-clinching stud, all loose hardware is eliminated from the applications.
